In the present study, the viscosity and refractive index of pure and aqueous 2-(methylamino)ethanol (MAE) and aminoethylethanolamine (AEEA) and an aqueous blend of MAE and AEEA were measured in the temperature range of 293.15–333.15 K with an interval of 5 K at atmospheric pressure. Amine content in aqueous mixtures varied from 0.05 to 0.30 weight fraction. The viscosity of pure components was correlated by Arrhenius-type equation with average absolute deviation percentage (AAD%) values of 1.87 and 2.42 for MAE and AEEA, respectively. Modified Vogel–Tamman–Fulcher equation with AAD% of 1.343 was proposed to correlate the viscosity of pure AEEA. A new equation with respect to temperature was also proposed to correlate the refractive index data of pure MAE and pure AEEA. Viscosity and refractive index data of aqueous MAE, AEEA, and an aqueous blend of MAE and AEEA were associated by newly proposed correlations and maximum AAD% was found to be 0.11 and 0.001 for viscosity and refractive index, respectively. Deviation in viscosity (Δμ) and deviation in refractive index (Δn D) from ideal solution of aqueous MAE and AEEA were correlated by the Redlich–Kister equation, and the maximum standard deviation was calculated to be 0.091 and 0.0012 for MAE and 0.114 and 0.0011 for AEEA, respectively.

“…For this work, 574 data points of 25 sets of amines that are relevant to CO 2 capture were collected. The list of amines is provided in Table S7 12‐61 . The collected data were divided into three categories: (a) molecular weight, critical temperature, and pressure as input data to identify the compounds; (b) temperature‐dependent properties such as density, viscosity, surface tension, and refractive index to correlate the dissociation constant values; and (c) p K a values as output data.…”

The dissociation constants (pK a ) of the eight amines, namely, N-(2-aminoethyl)-1,-3-propanediamine, 2-methylpentamethylene diamine, N,N-dimethyldipropylenetriamine, 3,3 0 -diamino-N-methyl-dipropylamine, Bis[2-(N,N-dimethylamino) ethyl] ether, 2-[2-(dimethyl-amino)ethoxy] ethanol, 2-(dibutylamino) ethanol, and N-propylethanolamine were measured between 298.15 and 313.15 K with 5 K increment. Based on the experimental values and using the van't Hoff equation, thermodynamic properties such as the standard state changes of enthalpy, entropy, and Gibbs free energy were calculated. Using computational chemistry calculations, the amine that is protonated first was predicted. Furthermore, computer-free group contribution methods such as the original Perrin-Dempsey-Serjeant (PDS), the modified PDS, and the Qian-Sun-Sun-Gao (QSSG) model were used to estimate the dissociation constants of the studied amines at 298.15 K. The QSSG provided the most accurate results. Finally, this work utilized an artificial neural network for estimating the pK a values, which were in excellent agreement with the experimental data.

Densities in the homogeneous liquid phase of (mono-)ethanolamine (MEA) and diethanolamine (DEA) were investigated using a commercially available high-pressure vibrating-tube densimeter (VTD). Due to the melting point of the experimental materials, the setup of the VTD had to be modified by an insulated housing of the entire piping including the pressure pump. The insulated housing could be heated up by a temperature-controlled heating fan. The liquid samples with a purity of (0.9994 or 0.9950) mole fraction, respectively, were decanted within an inert protective argon atmosphere and further degassed by several freeze–pump–thaw cycles. Density measurements were carried out at temperatures between (293, respectively, 313 and 423) K and at pressures between (5 and 90) MPa. The resulting 140, respectively, 120 (p, ρ, T) data points, explicitly extend the published database for MEA and DEA, with regards to pressure. A comparison with the currently used equations of state for MEA and DEA revealed a maximum relative deviation of – 0.18 % for MEA and – 0.41 % for DEA, each at the highest investigated temperature and pressure. Considering the measurement uncertainties in temperature, pressure, and oscillation period, as well as uncertainties resulting from the calibration and from the impurities of the sample, the combined expanded relative uncertainty (k = 2) in density varied from (0.1027 to 0.1038) % and from (0.1104 to 0.1130) %, respectively. The VTD was previously calibrated by comprehensive measurements of water and helium and had been further validated by measurements with pure propane.
